Why Using Pallets Is a Smart Way to Grow Watermelons Growing watermelons on pallets comes with some great benefits. By lifting the soil and vines off the ground, pallets improve airflow and drainage, which helps keep excess moisture away. They also naturally trap warmth, giving watermelon roots the cozy environment they thrive in. The biggest advantage? Keeping the fruit off the ground helps avoid rot, pest damage, and oddly shaped melons. Its a clever method, especially for small spaces or gardens with dense, wet soil.
